Precise digital positioning: 0–100% digital scale positioning provides fine, repeatable control over the device’s operating position for consistent results. Direct cable connection to the picture tube: the picture tube and the main unit are connected by a cable. During express shipment this cable can become detached; it may need to be reinserted by the buyer after delivery. If you are not comfortable with this possibility, please do not purchase. Directional control and adjustable speed: includes forward and reverse switches plus a potentiometer knob with integrated switch for adjustable control. Forward and reverse operation is supported; the standard forward/reverse switch can be replaced with a jog switch if preferred. Key benefits — why this product is useful Accuracy: Digital 0–100% positioning lets you set and repeat exact positions without guesswork. Flexibility: Forward/reverse control with an adjustable potentiometer gives both coarse and fine control in one unit. Serviceability: The cable connection design allows simple reattachment if it becomes loose in transit, minimizing returns and downtime. Important attributes Function: Digital position control (0–100%), forward/reverse drive control, potentiometer knob with switch. Compatibility: Designed to work with the connected picture tube via the supplied cable (cable may detach during shipping and must be reattached by the buyer). Customization: Forward/reverse switch can be swapped for a jog switch to suit different control preferences. Performance: Smooth variable control across the full 0–100% range with reversible direction. Practical applications CRT maintenance and repair: precise positioning and directional control for restoring or testing picture tubes. Retro arcade and monitor restoration: fine control for adjustments and calibration during restoration work. Electronics labs and prototyping: use for experiments or projects that require repeatable position settings and reversible motion control. If you need any additional technical details about compatibility or installation steps for reattaching the cable, please contact the seller before purchasing.
